The vast maritime and border territories stretch for thousands of miles, with scattered islands and a highly indented coastline. Complex meteorological conditions—such as sea fog, strong winds, and extreme diurnal temperature variations—continuously challenge the real-world performance of border security monitoring equipment. Conventional surveillance systems often suffer from blurry long range imaging, poor environmental adaptability, and difficulties in protocol interoperability, making it hard to achieve long distance target acquisition and seamless system integration. The Kaimorui CM8252LE ultra long zoom optical module, paired with the CM2001S encoding control board, integrates optical imaging and encoding control into a single, cohesive solution, delivering a high performance optoelectronic monitoring system for long range border and coastal patrols, target identification, and risk early warning.

I.52 Ultra-long optical zoom enables precise identification of distant targets in maritime areas.

Border and coastal defense duty requires both wide area patrol and continuous scanning of the coastline, as well as the ability to identify targets such as vessels, personnel, and drones from several kilometers away—both surveillance and target identification are indispensable. The CM8252LE is equipped with a 52× optical zoom lens, offering a focal length range of 15-775mm, with a 4-megapixel HD resolution, the DORI can detect targets at distances of up to 12,320 meters. In wide-angle mode, it swiftly scans the entire coastal zone; once a suspicious movement is detected, a single click switches to ultra long range zoom, rapidly magnifying distant objects to reveal critical details such as vessel markings and human actions.

The camera is equipped with a Sony Starvis CMOS image sensor, delivering color imaging at an ultra-low light level of 0.05 lux. Paired with an ICR infrared-cut filter for automatic day/night switching, it continues to produce crisp, full color images even in the faint light of dawn or dusk. A multi‑element aspherical optical lens assembly effectively suppresses chromatic aberration and flare at telephoto focal lengths; even at maximum zoom, the image remains sharp and clear, addressing the common issue of softness in high magnification shots with conventional telephoto lenses. This ensures that command centers can rely on clear, trustworthy visual evidence for remote analysis and decision making.

II.Operates reliably in harsh environments, tailored for round-the-clock monitoring on islands and tidal flats.

Island and coastal border areas are characterized by harsh environmental conditions—sea fog, sea surface heat waves, and alternating high and low temperatures—which can easily lead to image blurring, focus drift, and video jitter, creating security blind spots. The CM8252LE integrates temperature compensation, dual optical plus electronic defogging, heat wave correction, and electronic image stabilization, while supporting stable operation across a wide temperature range of –30°C to +60°C, making it ideal for all weather outdoor deployment in border and coastal security applications.

When sea fog blankets the ocean at dawn, the dual de fogging function penetrates the moisture to eliminate whitening and blurriness; when thermal currents on the water surface distort the image, the heat wave correction feature optimizes imaging. Image shake caused by sea breezes and gimbal vibrations is stabilized through electronic image stabilization. A stepper motor driven autofocus system delivers rapid response and precise tracking, continuously locking onto moving vessels at sea and low altitude drones without losing focus. With a durability rating of one million cycles—five times that of conventional brushless DC motors—the stepper motor ensures 24/7 uninterrupted operation, significantly reducing the frequency and cost of maintenance at island based stations.

III.Lightweight integrated design reduces the deployment load on coastal and maritime defense electro-optical gimbals.

Traditional long-distance surveillance solutions rely on a split type bullet camera paired with a telephoto lens, resulting in a bulky system that places extremely high demands on PTZ load capacity and mounting bases. Installation at elevated vantage points on islands is particularly challenging, driving up project costs significantly. In contrast, the CM8252LE features an integrated design that eliminates the need for an additional focus plate and comes factory calibrated for coaxial alignment. With a body length of just 32 cm—30% shorter than conventional designs—and a weight of only 3.1 kg—50% lighter—it substantially reduces the load on the PTZ mount.

The device is compatible with both large fixed optoelectronic pan tilt units and mobile pods, supporting a variety of border and coastal defense deployment configurations, including stationary island outposts and vehicle mounted mobile patrols. The core module features dual channel image output via LVDS and Ethernet, with H.265 encoded network streams that seamlessly integrate with command and control platforms, while LVDS output raw HD video feeds connect directly to the encoding board. It includes built-in ROI based image enhancement, customizable OSD, heartbeat signaling, and PTZ control, along with intelligent analytics such as tripwire intrusion detection, area entry alerts, and loitering detection. When abnormal targets are detected on shorelines or at sea, the system automatically triggers alarms, enabling proactive risk warning.

IV.CM2001S encoding control board, establishing a seamless communication link between the movement and the command platform.

The full potential of high-performance camera modules can only be realized with a stable, reliable encoding and control unit. The CM2001S encoding and control board serves as the central hub of the entire solution, seamlessly integrating with the CM8252LE to address a critical gap in system integration. Built on a 6-layer gold-plated military-grade PCB and equipped with industrial grade components, it offers robust electromagnetic interference resistance, making it well suited for the complex electromagnetic environments found in border and coastal defense applications. Via an LVDS interface, it connects directly to the camera module, automatically recognizing image signals without requiring complicated secondary development or debugging, enabling rapid deployment of image acquisition.

The hardware is equipped with dual RS485, RS232-TTL, I/O interfaces, and local buttons, and is compatible with SONY VISCA and PELCOP/D mainstream security protocol, with multiple adjustable baud rates, supportsCommand passthrough, power-off memoryAfter the device is powered off and restarted, it automatically restores the previous settings and PTZ status, ensuring that task configurations are not lost. It supports multiple SDI video output resolutions ranging from 720P to 1080P, with simultaneous connectivity to local monitors and forensic storage devices, enabling on-site viewing at the front end and remote transmission to the back-end platform. Additionally, it is compatible with a variety of VISCA protocol based camera modules and offers OEM/ODM customization, flexibly addressing the diverse requirements of coastal and maritime security projects such as island surveillance and mobile law enforcement pods.

With vast maritime borders, effective security hinges on long-range surveillance and seamless interconnectivity. The Camry CM8252LE ultra long zoom optical module, paired with the CM2001S encoding control board, delivers high definition imaging at great distances, robust performance in harsh environments, lightweight hardware, and stable, integrated system level control—forming a complete optoelectronic sensing closed loop for coastal and border defense. Designed for applications such as coastline monitoring, island observation stations, and border tidal flats, this integrated software hardware solution provides reliable, easily deployable technical support for remote surveillance of national land borders.
